[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 , the utility model provides a technical solution:

[0029] An automatic material suction device for PE cast film production comprises a material suction box 1 and a material storage barrel 7, wherein the material suction box 1 is provided with a pneumatic material suction device 5, a material suction pipe 6 is connected between the pneumatic material suction device 5 and the material storage barrel 7, an air pump 4 is also provided on the material suction box 1, an air inlet pipe is connected between the air pump 4 and the pneumatic material suction device 5, a material discharge port 13 is connected at the bottom end of the material suction box 1, a screen frame 8 is slidably connected in the material suction box 1, a filter screen 9 is fixedly connected in the screen frame 8, four support blocks 21 are symmetrically arranged on the inner wall of the material suction box 1, a detachable connection is formed between the support blocks 21 and the screen frame 8 through a detachable mechanism 2, and a filter screen 9 is fixedly connected in the screen frame 8. Two knocking mechanisms 3 are symmetrically arranged. The knocking mechanism 3 is located below the filter screen 9. The knocking mechanism 3 includes a support plate 37 and a motor 35. The support plate 37 is fixedly connected to the inner wall of the suction box 1. A sleeve 36 is fixedly connected to the support plate 37. A rack 32 is slidably connected in the sleeve 36. A second spring 310 is arranged between the bottom end of the rack 32 and the sleeve 36. A knocking plate 31 is fixedly connected to the top of the rack 32. The motor 35 is fixedly connected to the suction box 1. A rotating shaft 34 is fixedly connected to the output end of the motor 35. An incomplete gear 33 is fixedly connected to one end of the rotating shaft 34. The incomplete gear 33 is meshed with the rack 32.

[0030] Specifically, two second slide grooves 39 are symmetrically provided in the sleeve 36, and two second sliders 38 are symmetrically fixedly connected to the two sides of the rack 32, and the second sliders 38 are adapted to and slidably connected to the second slide grooves 39. The sliding connection between the second sliders 38 and the second slide grooves 39 makes the rack 32 slide more smoothly in the sleeve 36, and prevents the rack 32 from sliding out of the range of the sleeve 36, which affects the knocking process.

[0031] Specifically, the detachable mechanism 2 includes a semicircular block 27, which is slidably connected to the support block 21. Two first sliding grooves 24 are symmetrically provided in the support block 21. Two first sliders 25 are symmetrically fixedly connected on both sides of the semicircular block 27. The first sliders 25 are adapted to the first sliding grooves 24 and are slidably connected. A first spring 23 is provided between the side of the first slider 25 away from the screen frame 8 and the support block 21. A semicircular groove 26 is provided on the screen frame 8, and the semicircular groove 26 is adapted to the semicircular block 27. When the screen frame 8 squeezes the semicircular block 27, the first slider 25 slides in the first sliding groove 24, and the semicircular block 27 is retracted into the first inner cavity 22. At this time, the first slider 25 compresses the first spring 23. When the semicircular groove 26 moves to a position corresponding to the semicircular block 27, the elastic force of the first spring 23 is converted into a thrust to insert the semicircular block 27 into the semicircular groove 26, and the screen frame 8 is fixed and limited, that is, the installation of the screen frame 8 is completed.

[0032] Specifically, a sealing block 12 is fixedly connected to one side of the mesh frame 8, a pull plate 11 is fixedly connected to the sealing block 12, and a handle 10 is fixedly connected to the pull plate 11. The sealing block 12 seals the suction box 1 and improves the sealing performance. The handle 10 facilitates the disassembly and installation of the mesh frame 8 and improves the performance.

[0033] Specifically, an observation window 15 is provided on one side of the suction box 1 to facilitate observation of the interior of the suction box 1. When there are many impurities, the filter screen 9 can be pulled out in time for cleaning and replacement.

[0034] Specifically, a valve 14 is provided on one side of the discharge port 13. The valve 14 is opened to discharge the filtered material from the discharge port 13 to the production host for the production of PE cast film.

[0035] The working principle of this embodiment is:

[0036] When the device is in use, the air pump 4 supplies energy to the pneumatic suction device 5 through the air inlet pipe, and the pneumatic suction device 5 sucks material from the storage barrel 7 through the suction pipe 6 so that the material enters the suction box 1, and the material falls on the filter screen 9 for filtering and screening. When there is too much material and the filter screen 9 is blocked, the starting motor 35 drives the rotating shaft 34 and the incomplete gear 33 to rotate counterclockwise. When the incomplete gear 33 is engaged with the rack 32, the rack 32 slides downward to squeeze the second spring 310. At this time, the rack 32 is away from the filter screen 9. When the incomplete gear 33 rotates to a state where it is not engaged with the rack 32, the elastic force of the second spring 310 is converted into thrust, which pushes the rack 32 and the knocking plate 31 upward. Under the action of the second spring 310, the knocking plate 31 contacts the filter screen 9 and repeatedly knocks the filter screen 9 to knock the material in the filter screen 9 to prevent the filter screen 9 from being blocked.

[0037] When there are many impurities in the filter screen 9, the screen frame 8 is pulled outward by the handle 10, the screen frame 8 squeezes the semicircular block 27, and the first slider 25 slides in the first slide groove 24 to shrink the semicircular block 27 into the first inner cavity 22, thereby releasing the fixed limit of the screen frame 8, and the filter screen 9 can be cleaned and replaced.

[0038] When the filter screen 9 needs to be reinstalled, the screen frame 8 is reinserted into the suction box 1. When the screen frame 8 squeezes the semicircular block 27, the first slider 25 slides in the first slide groove 24, and the semicircular block 27 is retracted into the first inner cavity 22. At this time, the first slider 25 is compressed and the first spring 23 is compressed. When the semicircular groove 26 moves to a position corresponding to the semicircular block 27, the elastic force of the first spring 23 is converted into a thrust to insert the semicircular block 27 into the semicircular groove 26, thereby fixing the screen frame 8 and completing the installation of the screen frame 8.

[0039] Open the valve 14 and let the filtered material flow from the discharge port 13 to the production host to produce the PE cast film. The valve 14 can control the amount and speed of the material discharge.
